5-Norbornene-2,3-dicarboxylic anhydride, as a copolymer monomer in polyester can coatings up to 18.3 % w/w in the final dry coating, does not pose a safety concern to the consumer under sterilised conditions and prolonged contact with all foodstuffs (except beverages).
주요 응용
Nadic anhydride, also known as 5-Norbornene-2,3-dicarboxylic anhydride, is an organic anhydride derivative of norbornene. Besides its use as a component of polyester can coatings in foodstuffs, it is also used as an organic synthesis intermediate. 5-Norbornene-2,3-dicarboxylic anhydride (NA) can lower the cPC content of a polymerization reaction under zinc glutarate catalysis (3 MPa CO2, 60 °C, 0.8 wt% catalyst in neat PO) from 4.5% to about 1%, even if the anhydride concentration is as low as 0.3 mol%.
화학 반응
Bicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride reacts with methyl aminomethyllambertianate to give amide of bicyclo[2.2.1]heptan-1,2-dicarbocylic acid with a labdanoid substituent.
Safety Profile
Mild skin and severe eye irritant.When heated to decomposition it emits acrid smoke andirritating fumes.
